- Astrometry with GRAVITY
Astrometry is the branch of Astronomy, which deals with the precise measurement of celestial positions and motions. Amongst others, it has provided the most compelling and direct evidence for the existence of a supermassive black hole at the center of our Galaxy.
A novel astrometric instrument, GRAVITY, developed by the Max-Planck Institute for extraterrestrial physics, is currently put into operation at the Very Large Telescope in the Chilean Atacama desert. It allows probing general relativistic effects on stellar orbits and accretion physics in the vicinity of the supermassive black hole.
The goal of the master thesis is to study and calibrate systematic errors, which limit the astrometric accuracy. Known error sources are uncertainties in the telescope array geometry, the location of the laser metrology receivers at the telescope, and the exact time of the observations. Other effects are related to optical imperfections of the observatory, such as image and pupil motion. Furthermore instrumental effects like dispersion in optical fibers as well as polarization can impact the astrometry.
The master thesis will include analysis, calibration and interpretation of GRAVITY data. It might also provide the possibility to participate in an observing campaign at the Very Large Telescope interferometer in Chile.
